Prism Pro Mini CCT Fire Rated Downlight

When installing materials into a building against the potential risk of fire, there is a requirement to look at ‘Fire Reaction’ and ‘Fire Resistance’.

Fire Reaction constitutes a testing and classification process to determine the reaction to fire of building construction materials and in their contribution to the growth of a fire within a building.

Fire Resistance is an important and detailed requirement for buildings where fire resistance is expressed as the number of minutes of time duration where the building material and/or its component has the ability to withstand and resist the effects caused and result from a fire.

Light sources all have a colour temperature which will dictate whether the light emitted is either of a warm colour, an intermediate or neutral colour, a cool colour or a cold colour. The higher the colour temperature, the cooler, the colour appearance of the light source. The Colour Temperature is a description of the warmth or coolness of a light source. It is most simply, a method of demonstrating the colour characteristics of light, usually either as warm (yellowish) colour or a cool (bluish) colour.

The beam angle is the point at which the light output Lumens drop below 50% of the total light output. LED beam angles typically vary between 10° - 120°. The beam angle is the area where the light is at its most intense.

All light sources degrade over time. LM80 is the method for measuring how much lumen depreciation the light source will suffer. This is not to be confused with an estimation of life. LED's typically do not fail as they have no filament to burn to end their life, rather degrade beyond useful life output.
